LUMBER Application filed November This invention relates to vehicles andhas special reference to a lumbertruck.

llTOlGOVQl? the invention is an unprovement on the prior patents in thisline as evidenced by Patents 1, l22,958, 1,457,025 and 1,480,257.

In the former patented lumber trucks a cvlinder having a piston waslocated at each side of the truck both at the forward and rear endsthereof.

The principal objects of the present 1nvention are to do away with thesefour cylinders; the piping complications resulting therefrom; thepossible inequality of hoist due to unequal distribution of the load tobe carried by each cylinder; and tosubstitute therefor a single cylinderactuating the entire load hoisting mechanism in a novel and improvedmanner.

TVith the above and other objects in view as will be hereinafterapparent, the invention consists in general of certain novel details ofconstruction and combinations of parts hereinafter fully described,illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings l1ke charactors of reference indicate likeparts in the several views, and:

Figure 1 is a side elevatlon of a machine constructed in accordance withthe im proved invention.

Figure 2 is a s1de view of the improved arrangement removed from thechassis.

Figure 3 is a plan view of the improved arrangement, the wheels andother lower parts of the device being omitted.

Figure 4 is an end view of one end of the lumber supporting mechanism,detached from the remainder of the apparatus, it being a section on theline l4 of Figure 2.

Figure 5 is an enlarged detail on the line 5-5 of Figure 2.

Figure 6 is an isometric view of the control apparatus.

In the present embodiment of the invention there is shown a chassiscomposed of an upper frame 10 and a lower frame 11 which are connectedtogether by braces. At the forward end of this chassis there is providedthe usual wheel 13 on each side and at the rear end there are provided,similarly wheels 14:. These wheels are connected to the chassis by meansof the spring supports 15 described in the prior application and, therear wheels are driven by the previously CARRIER.

16, 1925. Serial No. 69,435.

described device comprising the rear sprockets 16, chain 17, sprocketwheel 18, chain 19 and sprocket wheel 20 which is driven from the engine21.

Whereas, it hasbeen heretofore known that the engine 21 could drive thecomprer sor which would regulate the elevation of the chassis, through aplurality of pressure cylinders, the present invention provides for theelevation of the load carrying parts of the invention by means of asingle cylinder. To the end there is provided a cylinder having thereina piston 23. This piston is connected on each side to a piston rod oneend of which is indicated at 24 and the other at 25. The piston rod 24is connected to a bell crank lever 26 which, by means of a link 27, isconnected to the upwardly projecting arrangement 28 of a load carrier29. While there is but one of the rods at, it is to be understood thatthe bell crank 26 is provided with a pair of arms 30 mounted on theshaft 31 and at each arm 30 is connected to a link 27.

Similarly the rod 25 is connected by a link 32 with an arm 33. Fixed ona shaft 3% which has a pair of arms 35 connected by links 36 to upwardlyextending members of the lift frame 29 as indicated at 37.

Thus the motion of the piston 23 in one direction or the other elevatesthe lift frame 29 or depresses the same.

There has thus been provided a simple and efficient device of the kinddescribed and for the purpose specified.

It is obvious that minor changes may be made in the form andconstruction of the invention without departing fromthe mate rial spiritthereof. It is not, therefore, desired to confine the invention to theexact form herein shown and described, but it is desired to include allsuch as properly come within the scope claimed,

Having thus described the invention, what is claimed as new, is

1. In combination, a chassis, a hydraulic pump thereon, -a singlecylinder receiving fluid from said pump, lumber elevating mechanism ateach end of the chassis and supported thereby, a piston in saidcylinder, a piston rod extending through both ends of the cylinder andhaving the piston mounted thereon, operative connections between eachend of said rod and the lumber elevating mechanisms at a respective endof said chassis.

iii)

2. In combination, a chassis, a hydraulic pump thereon, a singlecylinder receiving fluid from said puinp, luinher elevating nmcl'ianisinat each end of the chassis and supported thereby, a piston in saidcylinder, :1 piston rod extending through both ends of the cylinder andhating the piston mounted thereon, rock shafts eachjournalled on saidchassis to extend transversely thereof, a rock arm on each shaft, meansoperatively connecting each rock arm with a respective end of said rod,and other rneans operatively connecting each haft with the hunberelevating mechanism at a respective endof the 1,; chassis.

:3. in combination, a chassis, a hydraulic pump thereon, a singlecylinder receivingfluid from said pump, hu'n ber elevating mechanism ateach end of the chassis and supported thereby, a piston in saidcylinder, a piston rod extending through both ends of the cylinder andhaving the piston mounted thereon, rock shafts each journalled on saidchassis to extend transversely thereof, a

rock arm on each shaft, means operatively connecting each rock-arm witharespectire end of said rod, other rock arms on each shaft, and linksconnecting the last mentioned rock arms with the lun'iher elevatingmechanisms.

In testimony whereof I aliix my signature.

CARL F. GERLINGEH.
